There are mainly three ways for discharging the product after mixing:

1. Tilting Tank
   For small machines (MSG-1 to MSG-15), tilting can be done manually with a mechanical type (hand lever or hand wheel). For greater machines, electro-mechanically or hydraulically powered tilting system is supplied. MixerWorks supplies the feature that at tilted position, the blade will rotate at low speed (usually 20% of full speed) in reverse direction to aid the discharge by pushing two buttons with both hands.
   
   
2. Extrusion Screw
   The extrusion-discharge screw is located in the saddle section and runs in a cylindrical trough tangential to, and below the 2 mixingblades. During the mixing cycle the screw moves the material within the reach of the mixing blades, thus assuring a thorough blending of all the ingredients, and, at the same time, accelerating the mixing process. At discharge time, the direction of rotation of the screw is reversed and the mixed material is extruded through suitable die openings in the side of the machine. The extrusion screw has its own separate drive so that blades and screw operate independently.
   
   
3. Bottom Discharge
   The Sigma Mixers, since also used in pastes, reductions, and concentrates, can also be equipped with a bottom type discharge valve, which allows for discharge via two valves, located on each side of mixing trough.
